WRENCH.

SPECIFICATION forming part of Letters Patent No. 601,672, dated April 5,1898.

Application filed July 22, 1897. v Serial N0. 645,601. (N model.)

To all whom, it' may concern:

Be it known that I, JOHN G. NEWELL, a citizen of the United States,residing atv New Haven, in the county of New Haven and State ofConnecticut, Ahave invented certain new and useful Improvements inWrenches; 'and I do declare the following to be a full, clear, andexactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

lVIy invention relates to a novel form of wrench; and the obj ect is toprovide a simple, inexpensive, and eective tool of this character.

To this end the invention consists in the construction, combination, andarrangement of the device, as will bc hereinafter more fully described,and particularly pointed out in the claim.

wrench. Fig. 2 is a modified form of the same.

Fig. 3 is a longitudinal section. Fig. 4 is a transverse section on theline 4 4 of Fig. 1.

1 represents the rectangular handle of a wrench which is provided with atransverse pin 2, having a bearing in the slots 3 3, formed in theopposite walls of the yoke 4. The forward end of the handle 1 isprovided with an angular jaw 5, the transverse face of which is providedwith a series of ratchet-shaped teeth and the parallel face of this jawis also provided with a series of rearwardly-projecting ratchet-shapedteeth 7, adapted to engage the oppositely-disposed series of teeth 8 onthe contiguous edge of. the movable jaw 9. This jaw 9 hasa longitudinalmovement in the guide-orifice 10, formed in the yoke 4, and the parallelface of the movable jaw is also provided with a series of gripping-teeth11, oppositely arrangedto those in the parallel face of the jaw 5.

The lower end of the movable jaw 9 is providedwith a transverselimit-pin 13 to prevent the accidental detachment of said jaw from theyoke, and in adjusting the wrench Vthe head 5 is bodily drawn away fromthe 5o opposing jaw-shank, so as to separate the teeth 7 and 8 andpermit the adjustment of the jaws to correspond to the work to beperformed.

An auxiliary jaw 14 is pivoted on a pin 16 to the parallel face of themovable jaw 9, and its operative face is preferably smooth formanipulating finished nuts in contradistinction to the teeth 11, whichVare intended to grasp a pipe, bolt, or similar cylindrical object.

In practice I also provide a second auxiliary jaw 14', (shown in dottedlines in Fig. 3,) which is removably secured to the Iixed jaw, andeither, neither, or both of these auxiliary jaws may be employed, asoccasion requires. An integral web 17 is formed in the yoke 4 to form aguideway for the movable jaw,

and a leaf-spring is iixed by a screw or rivet 19 to the outer face ofthe handle 1, so that its free end impinges on the inner edge of theyoke to press the teeth 7 into engagement, with the corresponding teeth8 on the movable jaw 9.

`Although I have specifically described the construction and relativearrangement of the several ,elements of my invention, I do not desire tobe confined to the same, as such changes or modifications may be made asclearly fall within the scope of my invention without departing from thespirit thereof.

Having thus fully described my invention, what I claim as new anduseful, and desire to secure by Letters Patent of the United States, 1s

The combination with the slotted yoke 4, provided with the web 17, thehandle 1 provided with the leaf-spring 18 and the pin 2 on which it isfulcrumed in said slotted yoke, and the movable jaw 9, longitudinallyadjustable in said yoke, and provided with a series of teeth 11, adaptedto engage the corresponding teeth 7, on the handle 1, substantially asshown and described.

In testimony whereof I hereunto affix my signature in presence of twowitnesses.

JOHN G. NE WELL.
